Substitute Superintendent Alan Johnson says students and faculty work hard to make Woodland Hills High School a safe place for learning. "We're not going to sit by and allow the work that they've done to be tarnished by the actions of a few."

Two separate fighting incidents (involving several individual fights at once) were posted on YouTube involving students from Woodland Hills High School that spilled over into traffic. WARNING:the video is graphic in nature.

"I'd consider it a riot," Police Chief Greg Geppert said on Wednesday. He said as many as 60 to 70 people were involved on Monday and Tuesday afternoon at the intersection of South Braddock and Woodstock avenues, where students get off a school bus.

"The boys started taking their sweatshirts off, and the backpacks were thrown in the snow, and they went at it on my car, on the ground, in the snow," said a woman who was driving through the area with her preschool-age child. "They were swinging at each other, and some of them landed on my car and just were continuing fighting while I was honking and I was screaming and I was trying to get them away."

WTAE's Kelly Brennan reported that the brawl allegedly involved students and parents, and some of the students are juveniles. The video is too graphic for WTAE to show in its entirety.(Watch the video | See the photo slideshow)

"It was appalling," the school district's substitute superintendent, Alan Johnson, said Wednesday. "Over the past number of years, there has been a concerted effort by the board of directors, the administration, the faculty and, most especially, the students have all worked together to create a safe and secure environment at the high school, where students all feel welcome, safe and wanted, and the focus is truly on academic excellence. And something like this tarnishes that, and it shouldn't."

Noting that only a small minority of the high school's 1,300 students were involved, Johnson said the district must act "swiftly and decisively" -- which could range from suspensions to expulsions and arrests. "We are not going to sit by and allow the work that they've done to be tarnished by the actions of a few," he said.

"We have the video. Anyone who's viewed on that video as being involved, I'll guarantee you they're getting arrested," Geppert said.

At one point in the first video, there are as many as five fights going on at a time. One fight moved into traffic while cars attempted to drive around two men punching each other.

The second video showed a man in red pants walking toward another man who was trying to crawl up a hillside. The man on the ground was kicked in the head, sending him rolling backward down the hill.

"There were cars getting damaged -- just mayhem as far as the amount of students that are there. And as this is going on, we're watching more students getting off of buses," Geppert said.

Police believe the fights were planned, because several people were seen in the video waiting for action with cellphone cameras in hand. Two juveniles and an 18-year-old student identified as Aquan McEachern have been arrested so far.

"At least three of the people we see in this video are all pending juvenile cases coming up, that we've taken to Shuman (Juvenile Detention Center) and they're right back out. We can't keep them in there," Geppert said. "Unfortunately, with a lot of the Juvenile Court judges, we're getting no cooperation. We arrest them, they put them right back on the street, and this is the kind of instance that we're having with them repeatedly."

"I like Woodland Hills High School. Great kids come out of there," said the mother on whose car the students were brawling. "I mean, I don't know what to do. I really don't know what to do, but this cannot go on."
